An integral duct cap is provided to improve productivity without the waste of raw materials by using a mold and improve air conditioning efficiency by controlling the flow of fluid by a rubber gasket. A body part(100) is formed in the cylindrical shape with an opening(101) at a side by a mold. A stepped shoulder part(110) is formed on an outer peripheral surface of the body part in the proximity of the opening. A coupling shoulder(120) is formed on the outer peripheral surface of the body part to prevent the introduction of the body part into a duct. An indent part is formed between the stepped shoulder part and the coupling shoulder. A rubber gasket(140) is fitted into the indent part to closely contact the inner peripheral surface of the duct when the body part is connected to the duct.
